Research shows eggs from pastured chickens may be more nutritious | Penn State University
A study conducted by researchers in Penn State's College of Agricultural Sciences has shown that eggs produced by chickens allowed to forage in pastures are higher in some beneficial nutrients. In the research, titled "Vitamins A, E and fatty acid composition of the eggs of caged hens and pastured hens," which was published online this year in the January issue of Renewable Agriculture and Food Systems, researchers examined how moving pastured hens to forage legumes or mixed grasses influenced hen egg omega-3 fatty acids and concentrations of vitamins A and E.
